4. Configuración
4.1 Instalación da batería
The PeakTech P 3131 requires two 1.5V AAA batteries (included). To install or replace batteries:
- Asegúrese de que o dispositivo estea apagado.
- Localice a tapa do compartimento das baterías na parte traseira do medidor.
- Use un desaparafusador para abrir o compartimento.
- Insert the two AAA batteries, observing correct polarity (+ and -).
- Coloque a tapa do compartimento da batería e fíxaa co parafuso.
When the low battery indicator appears on the display, replace the batteries immediately to ensure accurate measurements.
4.2 Conexión dos cables de proba
Para o voltage, resistance, and continuity measurements, connect the supplied test leads:
- Insira o cable de proba negro no COM (common) input terminal.
- Insira o cable de proba vermello no VΩ terminal de entrada.

5. Instrucións de funcionamento
5.1 Encendido/apagado
Rotate the function selector dial from the "OFF" position to any desired measurement function to power on the meter. To power off, rotate the dial back to "OFF". The meter features an automatic power-off function (can be deactivated) to conserve battery life.
5.2 Medición de corrente CA/CC (Clamp)
To measure current without breaking the circuit:
- Xire o dial selector de funcións ata a posición A~ (corrente alterna) ou A= Posición (corrente continua).
- Preme o AC/DC button if you need to switch between AC and DC current modes (if the dial position combines them).
- Preme o CERO button to zero the display before measuring DC current, especially for small currents, to compensate for residual magnetism.
- Abre o clamp mandíbula premendo o gatillo.
- Enclose only un conductor with the clamp mandíbula. Asegúrate de que a mandíbula estea completamente pechada.
- Le o valor actual na pantalla LCD.

5.3 AC/DC Voltage Medición
Para medir voltage:
- Conecte os cables de proba como se describe na Sección 4.2.
- Xire o dial selector de funcións ata a posición V~ (Volumen da CA)tage) ou V= (DC Voltage) posición.
- Conecte as sondas de proba en paralelo ao circuíto ou compoñente que desexe medir.
- Le o voltago valor da pantalla LCD.
5.4 Medición de resistencia e continuidade
To measure resistance or check for continuity:
- Conecte os cables de proba como se describe na Sección 4.2.
- Xire o dial selector de funcións ata a posición Ω/))) (Resistance/Continuity) position.
- For resistance: Connect the test probes across the component. Ensure the circuit is de-energized.
- For continuity: Touch the test probes to the two points you want to check. A continuous beep indicates a low-resistance path (continuity).
- Lea o valor da resistencia na pantalla LCD.
5.5 Funcións especiais
- RMS verdadeiro: The meter measures True Root Mean Square values for AC voltage and current, providing accurate readings for non-sinusoidal waveforms.
- Retención de datos (H): Preme o H/MAX button briefly to freeze the current reading on the display. Press again to release.
- Maximum Value Hold (MAX): Manteña premido o H/MAX button to capture and display the maximum measured value. Press again to exit.
- Función CERO: Used to zero the display for DC current measurements to eliminate offset errors.
- Rango automático: The meter automatically selects the appropriate measurement range.
- Apagado automático: The meter automatically turns off after a period of inactivity to save battery. This feature can typically be disabled by holding a specific button during power-on (refer to the device's on-screen indicators or a more detailed manual if available).
